ALARM ATTACHMENT FOR OVERFLOW-BA SINS.

SPECIFICATION forming part of Letters Patent No. 357,307, dated February8, 1887.

- Application filed March 25,1886. Serial No. 196,511. (No model.)

To aZZ whom it may concern:

I ment to be applied tothe overflow-basins of refrigerators and tosimilar purposes. The alarm is constructed in such a manner that whenwater accumulates to a certain height within the basin it will raiseafloat and thereby liberate the mechanism which sounds abelL- Theinvention consists in the various features of improvements hereinaftermore fully r by lugs e,cut out from the body of plate 11 and aresecuredby means of rivets or solder. The

plate 0 is provided at its top with a hook, f, by which it may besuspended over the edge of a basin, A. At its bottom the plate 0 has anose or noses, g, to hold. it in an upright position.

.h is a spindle passing through and having hearings in plates a b. Thisspindle is surrounded by a coiled band-spring, Z, one end of which isattached to the spindle, while the other end is attached to a fixed drumor shell secured to the front of plate a. By revolving "the spindle thespring is wound up.

The spindle h, to which one end of the band-spring'i is attached,carries gear-wheel j, giving motion to said wheel j through an ordinaryconnection, such as a ratchet-wheel carried by the spindle and a clickcarried by the gearwheel, as soon as ratchet-wheel k is relieved, whensaid gear-wheelj revolves the ratchet-wheel k through an intermediatecogrevolution of the ratchet-wheel causes the hammer to be swung outward(to the left in Fig. 3) as a tooth of the wheel bears against theshoulder Z. liberated'the weighted head a causes-the hammer to swingback, and thus a rapid reciprocating motion is imparted to the hammer.

0 is a float pivoted to plate 0 by means of an arm having adownwardly-curved catch, This catch bears against one side of a pin, q,attached to head a and projecting through a slot of plate, I).

1' is a bell against which the hammer strikes.'

The operation of the'device is as follows: The clock-work being woundup, the appasuch a way that the float 0 projects into the basin. Thefloat is now in its lowermost position and the catch 19 is opposite thepin q and locks the clock-work. As soon as the float 0 has risen by anaccumulation of water (dotted lines, Fig. 1) the catch 19 will swingdown and the pin qwill thus be liberated to permit the clock-work tomove the hammer and to sound the alarm;

' I claim as my invention 1. The combination of bell r and plate 0 withspindle h, hammer m, having shoulder Z and pin q, and with float o,catchrp, gearwheel j, ratchet-Wheel 7c, and spring "Z, substantially asspecified.

2. The combination of bell r and plate 0, having hook f and nose 9, withfloat 0, catch 10, hammer m, pin q, spindle h, spring 2', gearwheel j,and ratchet-wheel k, substantnally as specified.

3. The combination of hell 1' and float 0, having catch 1), with hammerm, having weighted head n,.pin q, and shoulder Z, and with spindle h,gear-wheel j, and ratchetwheel 70, that engages shoulder Z,substantially as specified.

4. The combination of plates at b c with spindle h, gear-whee1 jratchet-wheel k, spring i, hammer m, having shoulder Z, head a, and pinq, and with bell r, float 0, and catch 19, sub: stantially as specified.
